In order to more clearly understand the above objects, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments may be combined with each other in the case of no conflict.

Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific details disclosed below. Example limitations.

The valve assembly, the cover assembly, and the cooking apparatus according to some embodiments of the present application are described below with reference to FIGS. 1 to 18 .

Embodiments of the first aspect of the present application provide a valve assembly. The valve assembly may be used in a cooking appliance having a cooking cavity or a component of the cooking appliance (eg, a lid assembly). As shown in FIGS. 1 and 10 , the valve assembly (specifically, it can be understood with reference to the valve assembly 10-2 shown in FIG. 2 and the valve assembly 10-3 shown in FIG. 11 ) includes a valve body 100 and a first Spool 200.

Specifically, as shown in FIG. 2 and FIG. 11 , the valve body 100 is provided with an air outlet 111 and a vent port 112 , the valve body 100 is provided with an air outlet port 113 that communicates with the air outlet 111 , and the valve body 100 is formed with an air outlet port 113 . 111 and the vent 112 are connected to the channel 120 . Wherein, the air extraction port 111 is configured to communicate with the cooking cavity, and the air outlet interface 113 is configured to be connected to the air extraction device 25 or to be centrally connected to the air extraction device 25 . For the central connection, for example, the air extraction device 25 and the air outlet 113 are connected via the control valve, so that the central connection between the air extraction device 25 and the air outlet 113 is formed through the control valve. The ventilation port 112 is used for external communication, and the communication can be macroscopically understood as direct communication or central communication, for example, the ventilation port 112 is directly opened and arranged to communicate with the outside world, or for example, the ventilation port 112 is connected with components such as the intake valve 26, The intake valve 26 and other components conduct the ventilation port 112 to the outside.

As shown in FIG. 2 and FIG. 11 , the first valve core 200 cooperates with the valve body 100 and controls the opening and closing of the passage 120 , so that the air outlet 111 and the air outlet 112 are connected or closed along the passage 120 .

As shown in FIG. 7 and FIG. 16 , in the valve assembly provided by the above-mentioned embodiments of the present application, when the cooking cavity needs to be pumped, the first valve core 200 can be used to control the opening of the channel 120 . When the time is turned off (ie, non-conductive), the air extraction device 25 operates so that the gas in the cooking cavity is drawn out along the air outlet port 113 after passing through the air extraction port 111 . As shown in FIG. 9 and FIG. 18 , when it is necessary to depressurize the intake air of the cooking cavity, the first valve core 200 can be used to control the communication between the ventilation port 112 and the air extraction port 111 , so that the gas enters the valve body 100 along the ventilation port 112 , and the gas entering the valve body 100 enters the cooking cavity along the air suction port 111, so as to realize the air intake pressure relief of the cooking cavity (of course, in some embodiments, it can also be understood as the cooking cavity along the air suction port 111, the ventilation port 112 exhaust to the outside to realize the exhaust pressure relief of the cooking cavity). Generally speaking, with this structure, while satisfying the airflow guidance and switching of the air extraction and air intake of the cooking cavity, the cooking device only needs to be provided with an installation port for assembling with the valve body 100 to realize the conduction between the air extraction port 111 and the cooking cavity. Compared with the structure in the related art in which at least an air extraction assembly port and an air intake assembly port are required on the cooking device, the number of openings is simplified, which is more conducive to simplifying the components of the cooking device (such as the pot cover or the cover plate 22 of the cooking device, etc.) At the same time, the assembly process of the product is simplified, and the strength of the cooking equipment components is better guaranteed, and the quality of the product is improved and the cost of the product is reduced.

In some embodiments, as shown in FIGS. 2 and 11 , the valve assembly further includes a detection element 300 . The detection element 300 may be an element suitable for detecting working parameters such as temperature, pressure and/or humidity. For example, the detection element 300 may be a temperature sensor, a pressure sensor, a humidity sensor, or the like.

In some embodiments, as shown in FIGS. 2 and 11 , the detection element 300 has a detection portion 310 . The detection part 310 may specifically be the part of the detection element 300 used for contacting the gas or the pressure object to be detected, such as the temperature probe part of the temperature sensor, the humidity probe part of the humidity sensor, the pressure sensitive part of the pressure sensor, and the like.

The valve body 100 has a suction head 130 , and the detection part 310 and the suction port 111 are arranged on the suction head 130 . In this way, by assembling the air extraction head 130 with the cooking device, the air extraction port 111 is communicated with the cooking cavity, so as to satisfy the air flow guiding and switching functions of air extraction and air intake in the cooking cavity, and the detection part 310 can detect the air flow in the cooking cavity. Operating parameters such as temperature, air pressure and/or humidity are detected. And by using this structure, the cooking device only needs to be provided with an installation port for assembling with the valve body 100 to realize the conduction between the air suction port 111 and the cooking cavity. As shown in FIG. 6 and FIG. The mounting port 22a of the body assembly is sufficient. Compared with the structure in the related art in which at least an air extraction assembly port, an air intake assembly port and a detection assembly port are required on the cooking device, the number of openings is simplified, which is more conducive to simplifying the structure of the cooking device components, and at the same time simplifying the product structure. The assembly process is better ensured the strength of the cooking equipment components, and the quality of the product is improved and the cost of the product is reduced.

In some embodiments, as shown in FIGS. 2 and 11 , the detection element 300 is partially accommodated in the suction head 130 . In this way, the overall integration of the valve assembly is higher, and the detection element 300 and the air extraction head 130 can be assembled with the cooking equipment components (such as the inner cover, the cover plate 22 , etc.) The detection element 300 is protected during the assembly process of the air extraction head 130 and the components of the cooking apparatus, thereby reducing the risk of damage to the detection element 300 during assembly.

In some embodiments, as shown in FIGS. 2 and 11 , the air extraction head 130 is provided with a first opening 131 , and the detection portion 310 is inserted through the first opening 131 and protrudes from the air extraction head 130 from the first opening 131 . In this way, the detection part 310 can penetrate into the cooking cavity to perform detection, so that the detection element 300 can detect the working condition parameters in the cooking cavity more truly and accurately.

In some embodiments, as shown in FIG. 2 and FIG. 11 , the first opening 131 is formed as an air suction port 111 and a first gap 132 is formed between the first opening 131 and the detection part 310 . In this way, the assembly form in which the detection part 310 extends out of the air extraction head 130 and the air intake function of the air extraction port 111 are realized, and the air extraction port 111 and the detection part 310 have better positional integration. As shown in FIG. 15 , the air extraction head 130 only needs a short portion to pass through the installation opening 22a and extend into the cooking cavity, so that the air extraction opening 111 can communicate with the cooking cavity and the detection part 310 can penetrate into the cooking cavity. That is, when the air extraction head 130 is assembled with the cooking equipment components, it is not necessary to protrude out too much, which can reduce the risk of the air extraction head 130 being collided or blocked by the food and other substances in the pot.

In some embodiments, as shown in FIG. 11 , the suction head 130 is provided with a suction port 111 at a position around the first opening 131 . This not only ensures the smoothness of the air intake of the air suction port 111, but also makes the distribution positions of the air suction port 111 and the detection part 310 approximately close, so that, as shown in FIG. This can reduce the risk of the air extraction head 130 being collided or blocked by substances such as food in the pot.

In some embodiments, as shown in FIG. 2 and FIG. 11 , a cavity is formed inside the air extraction head 130 , the detection element 300 is partially accommodated in the cavity and a second gap is formed between it and the inner wall of the cavity 134 , the second slit 134 is formed as a part of the channel 120 and communicates with the suction port 111 . In this way, while satisfying the purpose of conducting air flow, this structure not only improves the integration of the internal structure of the air extraction head 130 , that is, there is no need to design a separate structure of the channel 120 and the accommodating space of the detection element 300 in the air extraction head 130 , so that the The volume of the air extraction head 130 can be made smaller, which also reduces the contact area between the detection element 300 and the valve body 100, reduces the interference to the operation of the detection element 300, and improves the detection accuracy.

For example, as shown in FIGS. 2 and 11 , the air extraction head 130 is generally formed as an elongated cylindrical body, and the detection element 300 is substantially a columnar body and the extension direction is substantially the same as that of the air extraction head 130 . More specifically, the first opening 131 is formed at one end of the air extraction head 130 along the length direction, the end of the detection element 300 along the length direction is formed as the detection part 310 , and the detection element 300 is inserted through the extension direction of the air extraction head 130 . In the air extraction head 130 , the end of the detection element 300 is formed as a detection part 310 , and the detection part 310 extends out of the air extraction head 130 from the first opening 131 . A second gap 134 is formed between the detection element 300 and the inner wall of the air extraction head 130 . As shown in FIG. 2 , the detection portion 310 and the first opening 131 are gap-fitted to form first slits 132 distributed around the detection portion 310 , the first slit 132 communicates with the second slit 134 , the first opening 131 is formed as the air suction port 111 , and The valve body 100 inhales or discharges air from the first slit 132 . Alternatively, as shown in FIG. 11 , the air extraction head 130 is provided with air extraction openings 111 at the position around the first opening 131 , the number of air extraction openings 111 may be one or more, the detection part 310 is penetrated through the first opening 131 , and Interference fit or transition fit or clearance fit with the first opening 131 . Through the aforementioned design, the positional integration of the air extraction port 111 and the detection part 310 is realized. In this way, only one end of the air extraction head 130 extending from the head detection part 310 needs to be inserted into the cooking cavity along the installation opening 22a. The structure is simple and the assembly is convenient.

In some embodiments, as shown in FIG. 2 and FIG. 11 , the first valve core 200 is configured with an on-off action part 210 and an opening and closing cover linkage part 220 which are connected to each other. The on-off action portion 210 moves with the opening and closing cover linkage portion 220 , and the on-off action portion 210 serves as a portion of the first valve core 200 that is suitable for the conduction or cut-off of the control channel 120 . The opening and closing lid linkage part 220 can move, and the movement of the opening and closing lid linkage part 220 has a lid opening position and a lid closing position. The cover linkage portion 220 disconnects the control channel 120 of the on-off action portion 210 at the cover closing position.

For example, the action member for opening and closing the cover may specifically be one or more of the opening and closing button/cover opening handle 27/cover opening push plate, the linkage slider 24, the cover opening motor, and the cover opening electromagnetic push rod. The cover linkage portion 220 is a component suitable for cooperating with one or more of the aforementioned action members for opening and closing the cover, so that the first valve core 200 moves with the action of the action member for opening and closing the cover.

Among them, as shown in Figures 5 and 14, when the cover assembly is opened, the cover actuating member drives the latch 23 to unlock. As shown in Figures 9 and 18, the lid actuating member simultaneously drives the lid opening and closing linkage portion 220 to the lid-opening position, so that the on-off action portion 210 can be linked with the opening and closing lid linkage portion 220, so that the on-off action portion 210 can control the passage 120 to conduct, so that the cooking cavity can be inhaled or exhausted along the ventilation opening 112 to prevent the inside of the cooking cavity. It is dangerous to open the lid when under pressure or there is a problem with the suction pot. In general, the lid opening operation can simultaneously control the unlocking of the lock 23 and control the pressure relief of the cooking cavity, realize the one-key lid opening, ensure the safety of lid opening, and prevent the lid from sucking the pot.
